Resumen
In the western portion of the State of Goiás, Central Brazil, base-metal deposits typical of volcanic-plutonic arcs occur. Upto-date studies suggest that porphyry Cu-Au, (volcanogenic ?) hydrothermal exhalative Cu-Au and stratiform, submarine exhalative Au-Ag-Ba are present. Although restricted, the present state of knowledge on the geology and mineralizations of the magmatic arc indicates potential resources for metallic mineral deposits in the Brasília Belt.
